Kailis Rask is a member of Team Captivate. She is a non-Shiny Chinchilair.
Although she has fairly good physical attack, most of her moves are designed to disable the opponent or help her allies. Her Skill Link ability ensures that her Bullet Seed, Rock Blast and Tail Slap attacks all hit the maximum amount of times. She is also extremely fast.
Kailis is a perpetually upbeat and happy person, who always looks on the bright side of life. She is also rather gullible, and can easily be fooled into doing something for a bad guy, so long as he/she takes care to not present him/herself as evil, and tells Kailis that what she'd be doing is the right thing.
